Abstract: A self-propelled mower having a forwardly projected power unit containing a motor and mowing assembly, the deck is rotatably mounted on the axle of the machine so that the mower assembly can be raised and lowered in reference to the ground. The mower contains a riding unit mounted behind the axle. A linear actuator is secured to the riding unit that has an extendable rod which is coupled to the power unit by a pivoted link. The power unit is placed in a mowing position when the rod is extended and in an elevated position when the rod is retracted. The actuator is driven by a reversible electric motor that is controlled by a switch mounted upon the steering control of the mower so that the operator can raise and lower the mower without releasing the steering control.

Abstract: A self-propelled mixing and feeding machine on which the operator can ride. The machine comprises a wheeled, steerable chassis having a hopper mounted thereon. The hopper includes a mixing chamber provided with chain driven mixing means for the cattle feed. A discharge chamber is located in the hopper below one area of the mixing chamber. A feature of the machine is the low location of the discharge chamber and its discharge opening whereby the flow of feed is aided by gravity. Another feature resides in the novel means to minimize compacting of the feed in the vicinity of the opening between the mixing and discharge chambers. Still another feature of the machine is a means for quickly and easily replacing a discharge auger of one diameter with an auger of another diameter. When the machine is provided with an electronic scale that gives a digital reading of the weight of the feed in the hopper, another of its features is an independent suspension means for connecting the hopper to the machine chassis.
